Dr. Ibrahim Aben, a leading member of the Palestine Liberation Front, who was banned from all travel in the United States, has received personal approval from Canada’s Minister of External Affairs Mitchell Sharp, to visit this country, it was reliably learned here today. Dr. Aben’s admission to Canada was sponsored by George Haggar, president of the Canadian-Arab Federation who was deported from the U.S. two years ago. Dr. Aben was reportedly denied admission to the U.S. three weeks ago but, according to Haggar, “everybody in Ottawa was very cooperative.” He said he was told that Sharp personally gave official permission for the admission. Last week Sharp was attacked by delegates attending the Federation’s convention because they contended he represents a constituency in Toronto with a large Jewish population and, therefore, according to the delegates, cannot be objective in Arab affairs. They demanded Sharp resign. Dr. Aben, addressing a student meeting here yesterday, stated that any move by Egypt to reach a peace agreement with Israel will be viewed as an act of “capitulation” and will be fought by the PLF.
